Old Issues Portland Bridges and LA skyscrapers

I have a couple of issues that I have never fixed permanently and wonder what the solution is. The only way I can get the complete LA skyline is to install and activate QLRP4UT. All I have without it is a few generic bldgs here and there. However, if I activate QLRP4UT, I get the missing LA skyscrapers, but I also get double bridges at Portland, OR with FZ's KPDX scenery. I am sure most of you resolved these issues long ago (or maybe you never had them) but if anyone can recall how is the best way to resolve this, I would really appreciate it.
